Suprachoroidal implantation for the treatment of retinal detachment.

A temporary apposition of retina and choroid has been created during retinal detachment surgery by injection of sodium hyaluronate into the suprachoroidal space in 14 patients. The iatrogenic choroidal detachment lasts at least seven to ten days, allowing adequate time for retinopexy to permanently seal the retinal hole. Suprachoroidal implantation is compatible with and additive to conventional retinal detachment techniques, or it can be used alone as a primary treatment modality. Further clinical evaluation and development are necessary to establish indications and limitations for this technique.

A variable focus telescopic instrument for indirect ophthalmoscopy with increased magnification and stereopsis.

We devised a new binocular indirect ophthalmoscope and a complimentary examination technique that provide enhanced fundus magnification and optimum stereopsis through a wide range of patient pupillary apertures. The lightweight, mechanically simple instrument uses a variable focus Galilean telescopic observation system to enlarge the condensing lens image of the fundus seen by the examiner. The present device is capable of about X 1.5 fundus magnification with negligible stereopsis through a 20-mm patient pupil, continuously increasing to X 8.5 with greatly enhanced stereopsis through an 8-mm pupil. A zoom focusing capability considerably extends the magnification, stereopsis, and small pupip penetrating characteristics of a given condensing lens by allowing the examiner to binocularly observe the telescopically magnified fundus image throughout the 30-cm to 60-cm focusing range of the ophthalmoscope.
